History Manga / ACoupleOfCuckoos

* NotBloodSiblings: Despite the fact that Nagi and Sachi have been raised as siblings for most of their lives, finding out they aren't blood related has led them to begin thinking about each other more romantically. However, flashbacks have shown that people think they've been attracted to each other on some level even before the news broke out. [[spoiler:After the fake wedding, Ai admits that they never acted like siblings even as children, and Nagi tries to rationalize his feelings for Sachi and vice versa as a more complicated childhood friend romance.]]

** Sachi once agrees to a date with a boy in her grade, but only for the sole purpose of making Nagi jealous and worried over her.

* SwitchedAtBirth: Kicks off the series. Apparently no one bothered to tell either parents the sex of the child before whisking them off to the prenatal ward.

* ShipperOnDeck: Erika's father, weirdly enough, is willing to get Nagi and Sachi together despite the fact that he currently has the boy engaged to Erika. His reasons for supporting this are unknown. Erika's mother, on the other hand, is gung-ho about Erika and Nagi coupling, even ''kidnapping'' them for two weeks so they can [[YouNeedToGetLaid have sex]].

* OperationJealousy: Nagi uses his being confessed to by Ai in order to make Hiro jealous that he's been getting a lot of female attention lately. Subverted when Hiro gets ''annoyed'' instead of outwardly jealous, as he says all of this in the middle of her preparations for the annual summer festival and she's in no mood for love talk if he's not going to at least lend a hand.

* PrettyFreeloaders: Sachi eventually starts living in Erika and Nagi's house. Hiro ''also'' stays at the house for a time when she runs away from home, forcing Nagi to be moved to the storage room to sleep while Hiro got his room for the time being.

* SurprisinglyRealisticOutcome: The net results for Hiro and Nagi eloping is...nothing. They don't really have a game plan for running away from home, and when she has to confront her family on the matter, nothing Nagi says to her mother holds any weight. Erika is the one that fixes the problem, and even then she doesn't actually do much but get Hiro and her mother to actually talk about the arranged marriage offscreen. Hiro is still, by the way, engaged.

* BromanticFoil: Shion plays this role. He's shamelessly in love with Erika and firmly believes that he'll be able to set off a romcom-esque event with at least one of the girls surrounding Nagi, but reality shows that nobody cares about him that much.

* ArrangedMarriage: Introduced at the beginning between the two main characters. Hiro later states that she too has an ArrangedMarriage.

** When Nagi suggests that he and Erika met before and made a marriage promise in the playground as children, Erika waves the notion off entirely. The reason he suggest this is because he saw a picture of Erika and her older brother, and seeing that the guy looked a lot like him, reasoned that he must have met Erika somewhere.
